How to Clean Alkaline Battery Corrosion?

After having not used a battery-operated electronic device for quite some time, you might find that the item doesn’t work. Thinking that the batteries have run dead, you open the back to find the batteries caked with a chalky white substance that has a distinct metallic smell. Your batteries have corroded.

Thankfully, unless the damage is severe, you should be able to fix the problem. Cleaning the corroded area is simple, but work carefully so as not to burn your skin. You should prepare some tools: gloves, washcloths, white vinegar, a small bowl, cotton swabs, a small bowl of water,

1. Put on your gloves. Alkaline battery corrosion can burn your skin, so it is important to keep your hands covered.

2. Remove the battery and discard it.

3. Wipe away any large pieces of the corrosion with your washcloth.

4. Pour a small amount of white vinegar into your bowl.

5. Dip your cotton swab into the vinegar and rub it along the corroded area. The vinegar will dissolve the corrosion. Repeat until the corrosion is gone.

6. Dip your cotton swab into ordinary water and rub along the area that was corroded. This will help to remove any vinegar residue.

7. Wipe the area down with your second washcloth to make sure that everything is dry. The corrosion caused by the alkaline battery will now be gone.

If the electrical appliance is not used for a long time, please remove the battery. Although some electrical appliances are not in use, the internal circuit of the battery is connected, and the battery has been self-discharged. After a long time, there may be the possibility of leakage.
